Problems solved by technology

Although the 201510102332.5 patent mentions the underwater motor scheme, the specific structure of the transmission device is not clear, and the thrust bearing is not mentioned, which is incomplete. The 360° full-turn mechanism is too simple and only suitable for yachts

Abstract

According to the 360-degree full-rotation pod type underwater motor ship contra-rotating propeller propelling device, energy is saved by 20%, and the navigational speed and propelling efficiency are improved by 12% or above. An encoder, a special motor, a speed reducer and a reduction gear are adopted to achieve 360-degree full-rotation synchronization and non-synchronization whole-process electronic control of the propeller-rudder rotation body according to the advanced intelligent control theory, reversing is 1.6-1.8 times fast, and navigation is particularly safe. The underwater motor drives a transmission device to be connected with contra-rotating propellers, three components in the transmission device operate at the same time, the power and torque sharing proportion of the two contra-rotating propellers is calculated through the interdisciplinary innovation basic theory according to the speed ratio and the tooth number ratio, the contra-rotating propellers play the best energy-saving effect and efficiency in combination with the hydromechanics propeller pitch ratio theory, and the device is suitable for ships of any power type and military ships and boats, and solves the problems of high efficiency, energy conservation, environmental protection, noise reduction, vibration reduction and cost reduction of inboard and outboard ship contra-rotating propeller propelling devices which cannot be solved for many years are solved.

Description

Technical field: [0001] The present invention relates to a power propulsion device for motor boats, in particular to a 360° full-rotation outboard and outboard double-machine pod-type underwater motor that achieves the highest energy-saving value through a transmission device, which is the world's leading propulsion device for ships with contra-rotating propeller technology. [0002] 1. According to the invention of counter-rotating propeller by Swedish scientists 80 years ago, the practice and theory of research and development of ship counter-rotating propulsion device for 30 years and 15 years of test sailing on 6 ships have proved that the energy saving value of this invention is as high as about 20%, and the speed and propulsion efficiency are increased by 12% Above %, it is suitable for any type of boat with any power, especially for military boats. [0003] 2. The power supply of the underwater motor can be marine generator set or magnetic power generation, lead-acid ba...
